A pair of numbers used to locate a point on a graph?
A pair of numbers that are used to locate a point on a graph is called a ordered pair and is expressed as (x,y) where x is the location horizontally and y is the location vertically. For example the ordered pair (3,5) would be 3 to the right and 5 up away from the origin of the graph (0,0).
Is called a ordered pair================They are called coordinates. They need not be horizontal and vertical distances as suggested by the answer above. They could be polar coordinates which are the angle from the horizontal (anticlockwise), and distance from the origin.
What do you call an angle that exceeds 180 degrees?
An angle that exceeds 180° but is less than 360° is called a reflex angle.
What is the circumference of a circle with a 25ft diameter?
Use the equation
C = pi*d
Substitute
C = 3.14 * 25
C = 78.5 ft
NB This is only an approximate value, because '3.14' is only an approximate valuer for 'pi' , but convenient to use.
The other eq'n to use is
C = 2 pi r
Where 2r = d ( two radii equals one diameter ) . NB . 'radii' is the common noun plural of 'radius'. NOT 'radiuses'.
What is the ratio of the circumference of a circle to its diameter?
C = pi*d
The ratio is ALWAYS 'pi' for any circle, however, large or small.
pi is approximately 3.141592 , or 3.14, or 22/7
'pi' is an irrational number, which means the decimal digits go to infinity, AND the digits are NOT in any regular order.
To 'section' . However, if you mean two EQUAL parts, then it is 'BISECTION'.
What is the mathamatical meaning of bisect?
To cut or divide into two parts., To divide into two equal parts.
Does 81326 form a right triangle?
To determine if the sides 8, 13, and 26 can form a right triangle, we can apply the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) should equal the sum of the squares of the other two sides. Here, (26^2 = 676) and (8^2 + 13^2 = 64 + 169 = 233). Since (676 \neq 233), the sides 8, 13, and 26 do not form a right triangle.
What is the area of a circle in terms of its circumference?
C = 2 pi r
A = pi r^(2)
Hence
r = C /(2 pi)
Substitute
A = pi [C / (2pi)]^(2) or
Cancel down by 'pi'
A = C^(2)/ (4pi) ' Area in terms of circumference.
How much sides does a regular polygon have?
As many as you like.
However, being 'regular' all the sides must be of the same length.
The word ' poly' means 'MANY/.
How much sides a polygon have?
As many as you like!!!!!
The prefix 'poly' means ' MANY.
3 sides ; trigon ( triangle)
4 sides; tetragon
5 sides ; pentagon
et seq.,
What shape polygon has six sides?
An HEXAGON.
A Cube is NOT a polygon, it is a polyhedron; a 3-dimensional solid of SIX faces.
What kind of polygon is a cube?
A Cube is NOT a polygon.
A cube is a polyhedron;.
A polygon is a 2-dimensional figure of many sides
A polyhedron is a 3-dimensional object of many faces.
A Cube is an ' Hexahedron' , meaning a solid figure of 6(hexa) faces.
YES!!!
'poly' means 'many( faces'.
'Hedron' means a 3-dimensional object.
Hence polyhedron is a 'three dimensional object of many faces'.
What is the slope of the line that is perpendicular to the line whose equation is 2x - y equals 7?
-5
Factor the polynomial in quadratic form 6y6 - 5y3 - 4?
Let y^(3) = x
Hence y^(6) = x^(2)
Substitute
6x^(2) - 5x - 4
Factor
( 2x + 1)(3x - 4)
Substitute back
2y^(3) + 1 & 3y^(3) - 4
What is the sum of the interior angles measure of a 13-polygon?
EXT. ANGLE = 360/13 = 27.69...
INT. Angle = 180 - 27.69... = 152.31...
SUM of interior angles - 152.31... X 13 = 1980 degrees.
What is the area of a circle that has a diameter of 9 cm?
The area of a circle is figured out using the formula
Now, the circle we are given has a radius of 9cm. So, the area of the circle would be:
Area = 3.14 x (9)2
= 3.14 x 81
= 254.34 cm2
The area of the circle in question is 254.34 cm2
A quadrilateral is a parallelogram?
You have it the wrong way around. !!!!
A parallelogram is a quadrilateral .
Other quadrilaterals are
Squares, Rectangles, Rhombus, Trapezium, Kite, and irregular.
The word 'quadrilateral' means ' four sided'. 'Quad' Four and ;lateral ; sides'.
A right angle has how many degrees?
90 degrees. From which we have the word 'rectangular' meaning 90 degree angle. (NB 'Recta' ; Right).
